PATENT SAFETY BUTTON.

SPECIFICATION forming part of Letters Patent No. 371,707, dated October 18,1887.

Application filed April 14, i887.

To all whom it may concern:

Be it known that I, THEODORE REGEN- STEINER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use fulImprovements in Safety-Buttons; and Ido declare the following to be a full, clear, and exact description of the invention,such as willenable others skilled in the art .to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to separable and safety buttons, and has for its object the production of a button which can be readily applied to a garment, and which will prevent the material pulling or tearing out, as it is wont to do with buttons as are usually sewed on, and to construct a button which will be simple in its parts, efficient, and not liable to get out of repair.

The improvement consists in having the stem of the button provided with a plate at its inner or lower end, a spring-plate mounted loosely upon the stem, the nut to move the spring-plate relatively toward the fixed plate for clamping the cloth between the two plates when afiixing the button, the spring located within the upper portion of the stem,which is tubular, the flanges or plates extending inward across the end of the shank, leaving an oblong space or opening between their adjacent sides and notched on their under edges at right angles to the opening, and the separable head provided with a stem and a cross-head which is adapted to pass through said opening and be partially turned, so as tofit in said notches and lock the head in position, substantially as will be more fully hereinafter set forth.

The improvement further consists in the novel features presently to be described and claimed, and shown in the annexed drawings, in which- Figure l is a side elevation of a button of my invention; Fig. 2, an end view; Fig. 3, a plan View; Fig. 4, a front view of the key for screwing and unscrewing the nut on the shank of the button; Fig. 5, a sectional View. on the line x 00 of Fig. 3, the head of the button being Serial No. 234,792. (No modeli) removed, on an enlarged scale; Fig. 6, an end view of the shank only; Fig. 7, a cross-section of the shank on theline 7 7 of Fig. 5;; Fig. 8, a side View of the head of the button detached; Fig. 9, a sectional view on the line 37 y of Fig. 8; Fig. 10, a longitudinal sectional view of the upper portion of the shank on the line 2 z of' Fig. 5; Fig. 11, an edge side view of the head of the button as it appears at right angles to Fig. 8.

The button-shank A is provided at its lower end with the plate 13, which may be fixed thereon, or the lower end of the shank may have a conical-shaped head, a, and the plate provided with a corresponding countersunk opening to permit the passage of said shank and receive the head a, which will retain the plate in position upon the shank. The shank is externally screw-threaded for a short distance near the plate B to receive the nut D, and the plate C, loosely mounted upon the shank and confined between the nut and the plate B, curves slightly outward near its middle away from the plate B, so that when the nut is screwed up the cloth will be tightly clamped between the two plates. The nut is provided with notches (Z, diametrically opposite to each other, and the key G, centrally recessed to fit over the shank of the button, has projections g,which fit into said notches when screwing or unscrewing the nut. The extension projected from the bottom of the recess, is adapted to enter the upper end of the shank and steady the key in its movements. The upper portion of the shank is tubular, and its upper end is provided with inward extensions or plates E, leaving the oblong opening e between their adjacent sides. These plates or extensions are provided with notches e on their inner ends at right angles to the opening 6, for a purpose presently to be made known. The head F has a stem,f,

which terminates in the crosshead f, conforining to the opening 6. The length of stem between the head and cross-head must be equal or greater than the length of the plates or ex tensions E, so that the cross-head, after being passed through the opening 6, can be turned crosswise thereof and engage with the notches e by a slight outward movement of the head F.

. pressing outward forces the cross-head into said notches and locks the head in position. To remove the head, it is pressed in till the cross-head leaves the notches, and by turning the head one way or the other the cross-head will be brought in register with the opening through which it was inserted, when an outward pull will detach the head from the shank.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. In a button, the combination, with the shank having a head at one end and a plate at the opposite end, which end is threaded, of the plate 0, loosely mounted upon the threaded end of the shank, and the nut D, located 'between the head and plate 0, and screwed upon the threaded portion of the shank and bearing against plate 0, substantially as described.

2. The combination, with the shank having a head, as F, at one end and the conical-shaped head a at the opposite end, and a portion externally threaded near said head a, of the plate countersunk to receive the conical head, the second plate loosely mounted on the shank, and the nut located between the two heads and screwed on the threaded portion of the shank, substantially as set forth.

3. In the button herein described, the combination, with the shank having its upper portion tubular, and the plates located within said tubular portion, leaving an opening or space between their approximate sides, of the detachable head provided with the stem and the crosshead, substantially as set forth.

4. The combination, with the shank having its upper portion tubular, and the. plates located within said tubular portion of the shank, leaving a space or opening between their adjacent sides, and provided with notches at their inner ends, of the detachable head having a stem and cross-head, which latter is adapted to pass through said opening and become seated in the notches in the plates, substantially as specified. 5. The combination, with the tubular shank, the plates located within the shank and having notches at their inner ends, and the springs seated within the shank and arranged below said plates, of the head having a stem and cross-head, substantially as and for the purpose set forth.

6. The combination, with the tubular shank having a separable head at one end and a fixed plate at the opposite end, and a portion externally threaded near'said plate, the mounted plate, and the nut mounted on said threaded portion of the shank and having diametrically-disposed notches, of the key having a recess in one edge forming two branches, the projections extending from the ends of the branches, and the projection extended from the bottom 'of the recess parallel with and between said branches, snbstantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

THEODORE REGENSTEINER.
